To inform a monitoring person 502 of an event that causes a hindrance to traffic such as a cave-in of a road or an overhang of a tree on a road.SOLUTION: A point group image generation unit 513 generates, using three-dimensional point group data that includes three-dimensional coordinate values of respective measurement points located at a road and surroundings of the road, a point group image that is displayed on a display device on which each measurement point is drawn at a spot corresponding to the three-dimensional coordinate value of each measurement point. An event position calculation unit 515 calculates a three-dimensional coordinate value that corresponds to a designated spot which is designated in a displayed point group image and displays an event occurring on the road or in the surroundings of the road, as an event position, using the three-dimensional coordinate value of the measurement point corresponding to the designated spot. A map image generation unit 512 generates a map image which is the image of a map in which an event drawing indicating the event is added to a spot corresponding to the event position, and which is displayed on the display device.SELECTED DRAWING: Figure 31
【課題】道路の陥没または道路にはみ出た樹木などの通行に支障をきたす事象を監視者502に知らせる。【解決手段】点群画像生成部513は、道路および道路の周囲に位置する各計測点の三次元座標値を含んだ三次元点群データを用いて、各計測点の三次元座標値に対応する箇所に各計測点が描かれて表示装置に表示される点群画像を生成する。事象位置算出部515は、前記道路または前記道路の周囲に生じている事象を表していて表示された点群画像内で指定された指定箇所に対応する三次元座標値を、前記指定箇所に対応する計測点の三次元座標値を用いて、事象位置として算出する。地図画像生成部512は、前記事象位置に対応する箇所に前記事象を表す事象図が付加された地図の画像であり前記表示装置に表示される地図画像を生成する。【選択図】図31
